If, after checking the fuel and
cleaning the air filter, the engine still
will not idle, adjust the idle speed
screw as follows:
1. Start the engine and let it run at a
high idle for a minute to warm up.
Refer to Starting/Stopping.
2. Release the throttle trigger and let
the engine idle. If the engine stops,
use a small phillips or at blade to turn
the idle speed screw in, clockwise,
1/8 of a turn at a time (as needed)
until the engine idles smoothly.
NOTE: Checking the fuel,
cleaning the air filter, and
adjusting the idle speed should
solve most engine problems. If
not and all of the following are
true:
The engine will not idle;
The engine hesitates or stalls on
acceleration;
There is a loss of engine power.
Check the spark plug for proper gap
and condition. If problem still occurs,
have the carburetor adjusted by an
authorized service dealer.
MAINTENANCE
Some maintenance procedures may
require special tools or skills. If you
are unsure about these procedures,
take your unit to an authorized
service dealer.
Never do maintenance or repairs with
the unit running. Always do
maintenance and repairs on a cool
unit. Disconnect the spark plug wire
to ensure the unit will not start.
MAINTENANCE SCHEDULE
The required maintenance
procedures should be performed at
the frequency stated in the table.
They should also be included as part
of any seasonal tune-up.
CHECKING AND CLEANING
THE AIR FILTER
This should be done more frequently
in dusty conditions.
1. Accumulated dust in the air filter
will reduce engine efficiency,
increase fuel consumption and allow
abrasive particles to pass into the
engine. Clean the air filter with pure
gasoline every eight hours to maintain
in a clean condition.
2. Light surface dust can readily be
removed by tapping the filter.
3. Heavy deposits should be washed
out with a suitable solvent.
4. Remove the filter cover by
pressing the part of the inside cover
shown as Fig. 18.
CHECKING THE SPARK
PLUG
Use the spark plug wrench to remove
the spark plug (turn counter-clockwise
to remove).
Clean and adjust the spark plug gap
to 0.6
〜
0.7mm (Fig.19).
Replace any damaged or visibly warn
spark plug.
Install the spark plug finger-tight in
the cylinder head, and then tighten it
firmly with the spark plug wrench. If a
torque wrench is available, torque the
spark plug to 148-165inch-pounds.
WARNING: Never allow dirt or
debris to enter the cylinder bore.
Before removing the spark plug.
Thoroughly clean the spark plug
and cylinder head area. Allow the
engine to cool before servicing the
spark plug. Incorrect spark plug
installation can result in serious
engine damage.
CHECKING THE FUEL
FILTER
The fuel tank is fitted with a filter.
The filter is situated at the free end of
the fuel pipe and can be picked out
through the fuel port with a piece of
hooked wire or the like (Fig. 20).
FILTRO
Frequency Maintenance Required

exterior;
Inspect the engine, tank, and hoses for
possible leaks, and repair as necessary;

accumulation of dirt or debris, and clean as
necessary;
inspect the entire machine for damage, loose
or missing components or fastenings, and
repair as necessary.
Daily
Every 5 hours
Clean and re-oil the air filter.
Every 50
hours
Inspect the entire machine and tubes for
damage, including loose or missing
components, and repair as necessary;
Check spark plug condition and gap;
Check fuel filter.
Every 10/15
hours
Check spark plug condition and gap.
